雅砻江桐子林水电站引水防沙试验研究

Experimental study on water diversion and sediment prevention of Tongzilin Hydropower Station in Yalong River

本文通过水工模型试验研究了雅砻江桐子林水电站在不同拦沙坎高程、不同运行方式和敞泄拉沙下的引水防沙问题,并提出满足水电站取水防沙要求的有效建议.试验表明,采取合理有效的水电站运行方式亦或敞泄拉沙可以达到良好的引水防沙效果,满足工程规划设计要求.

Based on hydraulic model test,the properties of water diversion and sediment control of Tongzilin hydropower station in Yalong River under different top elevations of sand trap,various operation and opening gate for sediment release are studied and the effective suggestions for the requirement of water diversion and sediment control is proposed. The experiments show that ,to take reasonable and effective operations plans or open gate for sediment release can achieve a good flow guiding and sediment control effect and meet the requirements of the design.
